Start by upgrading to a 2.6.22.stable kernel.
If you still have problems with ACPI mode, then open a bug report here:
http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI
and attach the output from dmesg -s64000 from the default and acpi=off boots.
check that the driver to IRQ mapping in /proc/interrupts is the same
in both cases.
Look if there is a temperature reported under /proc/acpi/thermal_zone/*/temperature
and see if perhaps your system is getting hot when it fails. Make a note
if you can hear the fans turn on/off, and at what temperature.
provide the output from acpidump in the bug report.
thanks,
-Len
